Transfer Data Between Two Forms

[XADOOO]

Hello!

I have a "mainwindow" form named "program" and other form named "addstateform" which is created when I press a button on the "program" form. I want to collect the data from the "addstateform" to do stuff after this form is closed.
I've tried following this tutorial:
https://forum.qt.io/topic/19884/solved-issues-with-signals-and-slot-to-transfer-data-between-two-forms-code-included
But it didn't work. I'm also new to Qt so I don't understand very well the connect function and the signals and slots.

My code:

• addstateform.h
  (...)
  signals:
  void SendData(QString text);
  void SendString();
  private slots:
  void on_Done_clicked();
  (...)

• addstateform.cpp
  (...)
  void AddStateForm::on_Done_clicked()
  {
  QString text = "HI";
  emit SendData(text);
  emit SendString();
  qDebug() << "Signal Generated";
  this->close();
  }
  (...)

• program.h
  (...)
  public slots:
  void GetData(QString text);
  void GetString();
  private slots:
  void on_SMAddState_clicked();
  (...)

• program.cpp
  (...)
  void Program::GetData(QString text)
  {
  qDebug() << "Text Received: " << text;
  }
  void Program::GetString()
  {
  qDebug() << "Signal Received";
  }
  void Program::on_SMAddState_clicked()
  {
  AddStateForm ast;
  ast.setModal(true);
  connect(ast,SIGNAL(SendData(QString)),this,SLOT(GetData(QString)));
  connect(ast,SIGNAL(SendString()),this,SLOT(GetString()));
  ast.exec();
  (...)

I get this error in both "connect" lines:
no matching function for call to 'Program::connect(AddStateForm&, const char[14], Program* const, const char[13])'

I can't figure out what I'm missing/doing wrong.
Would appreciate some help and explanation. Sorry for the long post.
Thank you!

Hi,

It should be:

connect(&ast,SIGNAL(SendData(QString)),this,SLOT(GetData(QString)));
connect(&ast,SIGNAL(SendString()),this,SLOT(GetString()));

You need to pass the address of your QObject to the connect function
